Application Servers and Platforms
Exchange 2019 is not officially supported, but should work with the Mimecast Synchronization Engine. We're performing further testing, but until Exchange 2019 is officially supported, we are not responsible for any issues resulting from its use.

The recommended hardware requirements for a Mimecast Synchronization Engine site varies depending on the following factors:
- Total number of scheduled tasks
- Task type
- Schedule frequency
The minimum hardware requirements for a Mimecast Synchronization Engine site, in addition to the host operating systems requirements, are:
|Processor||2+ cores @ 2Ghz|
|Memory||4 GB RAM|
|Disk||At least 40 GB of available disk space, on the drive where the application is installed. It is recommended that: |
The following software is required for the Mimecast Synchronization Engine to install:
|Mimecast Synchronization Engine Version||PowerShell Version||.Net Framework Version|
The following network requirements must be considered:
- Mimecast Synchronization Engine must be able to communicate externally from your network to the Mimecast platform over HTTPS.
- The global discovery and regional service endpoints must be accessible from the server hosting Mimecast Synchronization Engine, with the global discovery endpoint accessible during the bind process, and the customers respective regional service endpoint accessible during normal operation.
The global discovery endpoint destination below is used during the bind process, and will need to be permitted where restrictions on outbound traffic are in place.
In addition, your regional service endpoint must be permitted, where restrictions on outbound traffic are in place.
Firewall and Proxy Considerations
The following firewall and proxy points must be considered:
- If your organization uses a proxy server or web filtering services, you should be aware that communications will be initiated by the NETWORK SERVICE account. Where proxy settings are enforced, ensure this is factored in during your implementation.
- To prevent issues with related to connection timeouts, an increase in the connection timeout period for half open connections may be required.
Host Server Considerations
The Mimecast Synchronization Engine must be installed on a member or standalone server. The choice on where to host the MSE depends heavily on the features that will be provisioned on the server.
Active Directory Synchronization
When provisioning a Mimecast Synchronization Engine site for Active Directory synchronization, the recommended location must be on the same LAN as a dedicated Domain Controller. This ensures the best performance for larger deployments.
Exchange Services: On-Premises Exchange
Applies to: Mailbox folder replication, calendar replication, mailbox storage management, and exchange managed folders.
With On-Premises Exchanges, the following must be considered:
- The Mimecast Synchronization Engine must be installed on same LAN as the Exchange servers, while having access to Active Directory Domain services in order to resolve objects, etc. Failed tasks and delays in the time scheduled tasks take to execute, may be observed if either Exchange or Active Director become unavailable.
- Access to a domain controller with the global catalog may be required in certain deployments.
- Ensure a fast and reliable connection from the Mimecast Synchronization Engine site to the target data source (e.g. Office 365, Exchange, File Servers, SQL Server, Active Directory, etc.).
The following must be considered with file archiving:
- The Mimecast Synchronization Engine should ideally be installed on same LAN as the file servers hosting the files being archived. Failure to do so may result in degradation in performance.
Instant Messaging (IM) Archiving
The Mimecast Synchronization Engine should ideally be installed on same LAN as the SQL servers hosting the Lync archive database you wish to archive. Failure to do so may result in a degradation in performance.
The Windows Service account that the Mimecast Synchronization Engine service runs under currently requires the English locale. For this reason, we recommend that you install the MSE on a server system set up via the US English installer media, and to configure the server to use the English time format settings.
The following group types are supported by the Mimecast Synchronization Engine:
- Distribution, but they must not be hidden from the Global Address List.
- Dynamic distribution, except when scoped to either the domain or forest level.
The following methods of grouping users are unsupported by the Mimecast Synchronization Engine:
- Organizational Units
